What version of Ionic are you building / using? Example in the blog was made for Ionic v3 and if you are using Ionic v4 it most likely will not work as you expect. Just saying.

Version is Ionic v4
Testing on Simulator

Have you contacted Josh about it? He is very responsive

Not contacted him. Is he on this forum.?
